The Jaeger-LeCoultre Master Reserve de Marche merges precision engineering with refined style. This is the reference 140.8.93.S, with a silver dial. In my opinion this is the best version of the Reserve de Marche, only 7.5 mm thick (even thinner than the "Ultra Thin" version) with a remarkable 45 jewels. This model was subjected to the Master Control process, where each watch undergoes 1,000 hours of testing to ensure accuracy, reliability, and durability, setting a gold standard in the realm of fine watchmaking. This watch is from 2001, and in casual testing (not in timegrapher, just checking against an atom clock after 24 hours) it shows a deviation of less than one second per day with its dial facing up. This Master Reserve de Marche comes on the original alligator band, with JLC clasp. No papers or box, but a brand-new, custom-made nubuck strap from Molequin is included. 37mm stainless steel case in attractive condition with only light signs of wear. Please see photos for condition. I am not a professional seller or photographer, so there are some reflections and dust on there. If you wonder about something you see, feel free to ask. The condition of the watch is excellent overall, with the original band showing some wear. Prefer to ship within Europe, but open to discuss other destinations. Price: 4,100 Euro + shipping.
